KOLLAR ATTORNEYS PORTABLE INFLATABLE ENCLOSURE FORPERSONAL USE BACKGROUND OF THE INVENTION This invention lies in thefield of portable enclosures for personal use and is directed to suchdevices which may be readily assembled and dismantled for storage ortransportation. It is more particularly directed to such a device whichhas a minimum number of parts which may be erected very quickly with noneed for special skills or manual dexterity, and which is sufficientlyrigid for general use in camping areas while utilizing very lightmaterials for the major part of the structure. More specifically, it isdirected to a portable enclosure in which certain of the functionalparts also serve, when appropriately connected, as a carrying case forthe other parts of the structure as well as some or all of theaccessories used with the structure.

Many types of portable enclosures are presently in use, ranging fromconventional tents to boxlike structures made up of a plurality of rigidplate members which must be secured together with many fastening deviceswhich require much skill and dexterity in assembly. Even a simple tentstructure calls for the securing of many loose parts and is verydifficult to set up without the services of two or more persons. Inaddition, when these various structures are dismantled, they are heavyand cumbersome to carry or to store.

SUMMARY OF THE INVENTION The present invention overcomes thesedifficulties and provides a construction which requires practically noassembly operations and which may be erected by a single person with nodifficulty. Moreover, it is readily dismantled and packed within its owncarrying case which is easy to carry and may be stowed in a minimumstorage space.

Generally stated, the structure comprises only three principalcomponents, a base member, a crown member, and a curtain. One marginalend of the curtain is peripherally secured to the margin of the basemember and the second marginal end is peripherally secured to the marginof the crown member. A plurality of elongate pockets are secured to thecurtain, extending substantially from end to end thereof and located inspaced parallelism around the major part of the periphery of thecurtain. A source of pressurized air inflates the pockets andautomatically erects the curtain to form a space-enclosing tubeextending from the crown to the base, with the pockets serving as ribsand stiffening the curtain sufficiently to make it self-supporting andresistant to light winds or inadvertent external contacts.

While one or both of the base and crown may be simple open frames toconstitute a minimum structure which may be hung free of the ground onany suitable support, in the preferred construction at least the base isa closed bottom, shape-retaining member of circular or rectangularplanform suited to rest on the ground and support the entire structure.One of the principal uses for which the invention is intended is as aportable shower. For this use the base takes the form of a pan having anupstanding marginal edge and a depressed central portion provided with adrain. A shower head within the enclosure may be supplied with waterfrom any source, such as a hose. In a more self-contained form, the panis made hollow to serve as a water container and may be pressurized bythe same pump which is used to inflate the pockets. The pump may be seton the floor of the pan to be operated from time to time by the occupantwhile he is taking a shower.

The crown member may have a closed top and depending marginal flange toserve as a roof and complete a total enclosure. It is of substantiallythe same size and shape as the pan so that when the curtain is deflatedthe crown and base telescope to form a carrying case in which thecurtain is stored, together with the shower head, pump, and otheraccessories. A handle is provided on the pan or roof to facilitatehandling.

The base, crown, and curtain are preferably rectangular in planform andone face of the curtain is divided to provide ingress and egress, themeeting edges being provided with a zipper to close the curtain when itis being used as a shower. A similar enclosure may be provided for useas a lavatory or toilet or dressing room. The second enclosure has asimilar zippered entrance on one face of the curtain, and a section ofthe opposite side may be omitted. The two enclosures are then securedtogether in facewise relation with the open section of the secondcurtain in registry with the zippered section of the first curtain, thetwo enclosures combining to make a complete toilet or bathroom facility,with direct internal access between the compartments. The zipper closureof the first curtain prevents shower water from entering the secondenclosure.

DESCRIPTION OF PREFERRED EMBODIMENTS The enclosure is generallyillustrated in FIG. 1, where it will be seen that in its preferred formit includes three primary components, a base member 10, a crown member12, and a space-enclosing curtain 14. While other suitable planforms maybe employed, the present construction has a generally rectangularplanform. The base member has a closed bottom 16 with an upstandingperipheral margin 18 to form a pan, while the crown has a closed top 20with a depending peripheral flange or margin 22 to form a roof. Curtain14 has a first lower end margin 26 peripherally secured to the margin 18of the base member and a second upper end margin 28 peripherally securedto the margin 22 of the crown member, the curtain thus having fourgenerally planar sides or strips combining to enclose the space betweenthe base member and the crown member.

The structure is rendered substantially self-erecting andself-supporting by the provision of a plurality of elongate pockets onthe curtain extending substantially from end to end thereof, the pocketsbeing inflatable to serve as ribs and stiffen the curtain. These pockets24 are arranged in closely spaced relation on three of the sides 30 ofthe curtain, and at least a few similar pockets are arranged at themargins of the fourth side 32 of the curtain as shown in FIG. 1. It ispresently preferred to form the pockets by utilizing two layers offlexible material in facewise relation and bond them together alongspaced parallel bonding lines 34 as indicated in FIG. 1. All of thepockets communicate with the end margins of the curtain so that they mayall be inflated through a single inlet. Even though the structure isrelatively rigid it is very light and is subject to displacement by thewind or by external contact. The roof and pan are therefore providedwith loops 36 for connection to any suitable tiedown devices.

lngress and egress are made possible by forming the major part of thefourth side 32 of the curtain from portions 38 and 40 which are integralwith the remainder of the curtain but separable from each other along avertical line provided with a zipper or other fastening means 42 tomaintain them closed during use. A pair of similar fasteners 44 near thebottom end facilitates the opening.

The enclosure of the invention is made truly portable by virtue of thefact that the curtain may be folded and stored in the base member 10,with crown member 12 being telescoped over the base member to form thecarrying case shown in FIG. 2. For this purpose member 12 is made withthe same planform as member 10, and its margin 22 is just enough largerthan margin 18 to provide a sliding fit. A handle 46 is formed on memberto facilitate carrying the packed case. For convenience in packing, thecurtain is provided at some or all of its four corners with zippers 48extending almost from end to end which open to divide the curtain intoseveral strips which are much more readily folded.

Any suitable material may be used for the structure but it is desirablefor lightness and ease of manufacture to make the curtain of plasticsheets and the base member and crown member of molded plastic. Both thecurtain and the crown member may be translucent to admit natural lightto the enclosure.

One of the principal purposes of the enclosure is for use as a shower incamping areas, and therefore it is preferably provided with theadditional features illustrated in FIGS. 3, 4, and 5. Although thecurtain may be fastened to the base member and crown member bymechanical fasteners such as hooks and loops or eyes, it is desirable tocontrol the outflow of water when the enclosure is used as a shower. Forthis purpose the upper and lower end margins 28 and 26 are bondedthroughout at least a major part of their periphery to the innersurfaces of the margins of members 12 and 10.

As seen in FIG. 3, a bracket 50 is mounted on one of the walls 30 of thecurtain to support a shower head 52 provided with a valve control handle54. A hose 56 leads from the shower head to a source of water supply.Soapdish 58 may be an inflated portion of the curtain wall. A baglikewaterproof sheath 60 hangs along another curtain wall to contain adressing robe and towel. Drain 62 is provided in the floor of the basemember to conduct wash water to the exterior. If the water supply is tobe external, as from a hydrant or portable tank, the bottom 16 of member10 may serve as a reservoir for waste water or be solid or foam filled.

The self-contained character of the construction is preferably furthercarried out by making base member 10 generally in the manner illustratedin FIG. 4, where is will be seen that member 10 is provided with a floor64 spaced above bottom 16 by ribs 66 to form a container for storingsufficient water to supply the shower head for one or more persons. Airunder pressure is supplied to fitting 68 to pressurize the water andforce it out through fitting 70 to which hose 56 may be attached toconduct the water to the shower head. The ribs 66 are provided withapertures 72 at their lower edges so that all of the water will flow tothe lower end of fitting 70 as additional air is forced into thecontainer.

If an outside supply of water is available, the lower end of hose 56 maybe removed from fitting 70 and applied to fitting 74 which passesthrough the curtain and may be connected to an outside source such asline 76. When the water in the base member container is to be used, afoot-operated air pump 78 is provided and is connected by hose 80 to airinlet fitting 68. The same pump is initially used to inflate the pocketsand erect the enclosure by connecting its hose 80 to the inflationfitting 82. The supply of water in the container is replenished throughfitting 84 having a cap 86 which may be mounted flush rather than asshown. 7

To avoid excessive steaming up of the shower during use, the roof 20 isprovided with a vent opening 88, and flap 40 is provided near its lowerend with a fresh air intake screen 90. The screen may be made of Teflonor other hydrophobic material, or may be of any material with ahydrophobic coating on at least its inner face to prevent water fromsplashing or running out through the screen. It will be-noted that vent88 is vertically in registry with filler 84, andthat a portion of endmargin 28 of the curtain is not bonded to roof margin 22 adjacent to thevent. Thus, when the structure is dismantled, a curtain portion isdisplaced inwardly and the tiller and its cap will protrude through vent88 when the roof and pan are telescoped. With this arrangement, the panmay be filled whenever it is convenient while the structure is in packedcondition. The pan 10 may have a heat-absorbing external surface so thatthe water contained therein may be heated by solar radiation before theenclosure is set up.

There is always a possibility that the inflatable curtain wall will bepunctured with no facilities momentarily available to repair it. To dealwith this eventuality, sockets 92 are provided in the corners of margins18 and 22 of the pan and roof, and telescoping brace rods 94, withpushbutton latches 96, are provided to be inserted in the sockets ofsome or all of the corners to support the roof until repairs are made.

A simple basic, or minimum, enclosure is illustrated in FIG. 6. In thisconstruction, the base member 98 is made as a simple open frame from rodor tubing 100. The curtain 14 may be secured to the frame with a seriesof rings 102 and the frame may stand on the ground or the entireenclosure may be supported by rings 36 from any suitable overheadsupport. The roof 12 is similar to that of FIGS. 1 and 3, but it may bereplaced by an open frame similar to base member 98.

A pair of enclosures as described above may be readily combined to makea complete bathroom facility. As indicated schematically in plan in FIG.7, a first enclosure 104 having zippered flaps as shown in FIGS. 1 and 3may serve as a shower. A second similar enclosure 106 may be set up withone wall in facewise adjacency to the zippered wall of enclosure 104,and the two structures secured together to form a compartmented shelter.Enclosure 106 is provided with a stool 108 and a basin or vanity 110.The entry 112 is provided with zippered flaps similar to those ofenclosure 104 while its opposite wall has an uncurtained opening 114 inregistry with the flaps of enclosure 104. Thus, the two units are opento each other but may be segregated when the shower is in use.

In FIG. 8 is shown a water container supported upon a stand 122. A gasnozzle 124, suitably connected to a source of fuel 126, is disposedwithin a recess formed in the bottom of the container 120. The waterwithin the container 120 may be suitably heated upon supplying fuel tothe nozzle 124. Air pressure is supplied to the container 120 via thetube 128 and water is conveyed from the container by outlet tube 130.The container 120 is constructed with a fill cap 132 to permit thefilling of the container 120 with water. The fill cap 132 preferablyincludes a temperature gauge having a conductor portion 134 forindicating the temperature of the water within the container 120. Itwill be appreciated that the footoperated air pump 78 (as shown in FIG.5) may be connected to the tube 128 and the outlet tube may be connectedwith the line 76 shown in FIG. 5. It will also be appreciated that thebase 10 as shown in FIG. 4 may be constructed similar to the container120 shown in FIG. 8 and serve as a reservoir for the water prior toheating thereof. Understandably, the handle 136 shown in FIG. 8 would besuitably relocated, a suitable recess would be formed for installing theflame nozzle, and the stand 122 could be dispensed with entirely.

It will be apparent that the present invention provides a simple,compact, and readily portable enclosure for personal use and which maybe readily duplicated to provide a complete bathroom facility which maybe set up and dismantled quickly and easily in any suitable campinglocation. For example, if desired, the curtain 32 may be formed withoutthe vent 90 and the portions 38 and 40 may be formed of a reduced lengthsuch that the lower margin 26 of curtain 32 does not come in contactwith the upper surface of the base 10, Under these cir cumstances, thelower margin 26 would preferably be reinforced or stiffened to preventsame from buckling. It will also be understood that the bonding lines 34may be interrupted at predetermined locations to facilitate bending ofthe curtain along predetermined lines. Additionally, it will beappreciated that the base and crown sections 10 and 12 may be formedfrom the same mold and, thus, said sections would not be telescopablymounted one within the other. Additionally, the fitting 34 and cap 86could be installed adjacent the handle 46, the length of the recessformed in the crown section 12 being suitably increased to accommodatesame if said fitting and fill cap are not mounted flush within the basesection 10. Although FIG. 3 shows the use of cylindrically shapedtelescoping brace rods 94, it will be appreciated that brace rodsrectangular in cross section could be used, such use requiring only thatthe sockets 92 be formed also rectangular in cross section. Finally, itwill be understood that the second enclosure 106 as shown in FIG. 7 maybe provided with zippered flaps at the entry 112 and the opening 114 or,if desired, the opening 114 may be provided with a removable curtainsection.
